IMPROVEMENT IN' STEAM-CYLINDER mOILELR.

The Schedule referred to inthese' Letters Patent and making parl: of thesame.

To all whom it 'may concern v Be it known that we, SIMON F. STANTON, of-Manchester, in the county of Hillsborough, and State' of New Hampshire,and OnvILLE RIPLEY, of Charles accompanying drawings, forming a part ofthis specication, in which- Figure 1 represents a perspective outlinevie'w of this invention.

Figure 2' represents a sectiOnalVeW, showing its working parts.

Figure 3 is a plan or rear view of the piston.

Figure 4 is a -view of the front of thesa'me.

Similar letters of reference indicate likeparts.

lThis invention relates to a stationarybiler, surmounting the top oflocomotive-engine boilers, near the smoke-stack, having a reservoir andsuitable means for conveying the. oil from 'the same to 4the steamchestsfor lubricating the cylinders, without the engineer or fireman leavingtheir cab for this purpose.

A, ig. 2, represents the reservoir, made of sheetmetal, its seamssoldered, or it maybe cast of one piece of meta-l, its inlet closed'by acap, V, and its outlet, A', an open port, communicating with :thecyliuder- B.

B is the cylinder, cast of one piece of metal, having three openings,one at the top, through which the oil passes and enters from thereservoir, the second, which is'covered by the cylinder-head W', andserves as a guide for the piston-romand the third at its furtherextremity, which opens" into the outlet-chamber,'aud also forms the seatfor the valve H, which closes the same.

Gis the pelforatedpiston closed by the valve K, which 'piston forces theoil out of the 'cylinder into the outlet-chamber P, and thence into theconductingpipes. Y

D is the paititioned tubular piston-rod, which receives, at itsforwardend, ,by a screw-tl'u'ead, the shank of the piston, and through that thevalve-stem I and nut J. At the other extremity is received the hollowguide-plug Fand the rod E, encircled by a spiral spring, G;

Eis the connecting-rod operating the'piston, extending from the interiorof the piston-rod to the in terior of the cab, where it terminates, andis secured by any well-known device, which is releasedby the engineerand thrust forward whenever he wishes to discharge the oil from thecylinder.

F is the'hollow guide-plug, screwed into the rear end of the tubularpiston-rod, which serves to. guide the rod E, and prevents itswithdrawal entirely by means of the stud on the end of the rodE, alsocon* fining the spiral spring G within thecavity D2.

G is a spiral spring encircling the rod E, Within the cavity D2. Itcompensates for any accidental movement communicated tothe rod E, byoscillation of the cab, within which the other end of the rod E issecured by any of the well-known devices.

H is. the valve closing the outlet of the cylinder B, and operated bythe piston'G, nut J, and tubular rod D.

I, the valve-stem, retained within the' cavity of the piston-rod D1. bythe nut J. y

J, the nut on .the valve-stem.

K, the piston-valve, which opens when the piston is withdrawn, andcloses when thrust forward.

LL are thepelforations through the face of the piston C, which permitthe passage of the oil through them into the forward part ofthe cylinderB, when the valve K is open.

M M areheaded screws or rivets, which keepin position the valve K.

N is the packing-box, screwed on to the cylinderhead WV.

0 is the packing around the piston-.rod D.

P is the outlet-chamber, screwed on to the forward end of the cylinderB, and which receives vthe oil as forced from the cylinder B,andjdelivers it through an open port on each side Q Q, fig. 1, into theconducting-pipes It R.- f

Q Q are the openports 'of the outlet-chamber l?.

1t -lt are the tubes or pipes which convey the oil from theoutlet-chamber l domi into the steam-chests Von each side of the boiler.

S is the steam-jacket enclosing the cylinder B and its contents, andnearly covering the bottom of the reservoir A. Steam is admitted throughthe hollow plug T. The oiiicc of this device is to keep hot and at auniform temperature the oil, tallow, or other lubricants containedwithin the reservoir A and cylinder B.

' T is the hollow plug, screwed into the top of the boiler, and isconnected to the jacket by the screwcoupling U. The amount ofsteamadmitted through the plug may be regulated by valves.

U is the screw-coupling connecting the plug T and steam-jacket S.

V is the screw-cap, or stopper, closing the inlet of the reservoir A,and is removed for lling the same.

W is the cylinder-head.

Various methods 'of packing the piston may be employed. lVe have foundthe common metallic ring to answerthe purpose better than others in use.

The prime object of this invention is economy in the use of oil or otherlubricants, when applied to locomotive-engine cylinders.

Itwill be seen from the explanation of our invention that the cylindersmay be lubricated simultaneously,A by either the engineer` or fireman,without leavin g their cab, by simply thrusting forward the con-`nectingrod E, whichis accessible to them within the cab at all times. y

Having thus described our invention, We claim, and' desire to secure byLetters Patent- Zl. The arrangement of the reservoir A, the cylinder B,outlet-chamber P, and conducting-pipes R R, when constructed in themanner herein described.
